I love these sandals, they are beautiful. Normally I am Size 39, so I ordered both a Size 39 and 40. It is recommended to size up in this label, which I found worked perfectly for a previous pair of Ancient Greek Sandals. Whilst the Size 40 fit in the length, I found them too tight across the front toe strap. Perhaps it may stretch out, but I found it a little uncomfortable as the strap sat low on my toe. My toes are normal sized, not wide either.
